Do you ever?

When you see a sign like this, do you ever think to yourself, "What if I do open it? Will the alarm really sound?" Do you ever for just even half a second think about opening it? I'm not talking about seriously contemplating doing it...just letting the thought briefly run through your head, or I guess maybe if you are Allen, serious contemplating it... Why do we? What is it about human nature that makes us want to test things like this? Like when we are children and we are told not to do something. Sometimes we did it, not because we wanted to be bad, but we wanted to find out why not, or what happens if I do?
